4-11 Image Processing
Image Processing Pipeline
.
The IL3 image processing begins in the LUPA1300-2 sensor, where on-chip column FPN corrections occur
(if enabled) and the Black level is set using data collected during calibration. Pixel data, also collected
during calibration is used for Pixel FPN correction (if enabled). (See “4-6 Black Level Calibration” on page
29.) The IL3 does more image processing internally, some of which can be controlled by the operator.
To better understand how this works, please refer to “Figure 4-16: Select Per Frame Metadata in View
Menu”.
The 10-bit sensor output goes to the Bit Selector, then to internal high-speed memory. This selection is
made by the user when bit depth is selected. (See”4-3 Setting Bit Depth” on page 27.)
The path for all images and the input to the histogram is: Sensor, to Bit Selector, to Image Processor, to
Display / Histogram. It is always 8-bit Mono or 24-bit Color. Live images pass through from high-speed
memory to the image processor immediately. Captured images are saved in high-speed memory until
the camera powers down or the images are written over.
•
Images in the internal high-speed memory have not yet gone through the image processor. This
means that the image processing settings have NO effect on the images in high-speed memory--
they only affect the images as they are saved or displayed.
•
Images in high-speed memory may be viewed or saved multiple times with different settings.
